Anrrc CITY, NEW nBsnY :BURGLARPROOFLOGK Application filed February i This invention relatesto a lock, the general object of the invention being tosoform the casing that the lock resembles a watch and to so construct and arrange 'the parts-"of the 5 look that the keeper members are entirely concealed sothat it is impossible to reach suchmembers in an attemptto saw'or other Wise damage the same, and this arrangement also eliminates hasps and shackles whichare Another object of-the invention is to make thelock waterproof so that the interior parts will not become rusted or otherwise damaged by rain or moisture entering the casing.

A further object of the invention is to provide aT-shaped bolt having a pair of keeper engaging members thereon, thereby providing a double arrangement forconnectingthe lock with a pair of keeper members, wlth 20 key or otheroperated mean bolt in looking position.

, This invention valso con's'i sts in certain other features of construction .and inith'e'combi v nation and arrangement ofthe several parts, Ito be hereinafter fully descrlbed, illustrated in the accompanying drawings and: specifi-- cally pointed out in they appended claims.

, In describing the invention infdetail, reference willv be had to the accompanying drawings wherein like characters denote'like or corresponding parts throughout, the'several views,,and in whichz Figure 1 is a view, showingth "W ter at einvention in use for looking a pair of members together. is a vlew of the rear vface ofthe 3 his a vertical sectional; view as '5 -'15 or l ct bf foh th 6% s]? {rig-v a] sea-1 a 'ni use t 7 f rigs a fragmentary view showing Figure 9 is a view showin'ga modification.

Figure 11 is a sectional view through the lock, showing another modification. v In thesedrawingathe letters 'A and B indicate a pair of members to be locked;together,'each member having a plate 1 thereon which is formed'with a keeper 2 having a downwardly tapering hole 8 therein er circular shape in cross section. p Thelock comprises a casing 4, with a cover plate 5 suitably attached to its rear face,

7 this casing being made in the form of a v watchand if desired, theiro'ntof the casing may have thereon the representation of a watch dial-and its hands so thatthe device will simulate a watch,and I prefer-to'call the lock aj. 'burglarj-proof watch lock, ,aslit simulatesa' watch. i

The c'o'verfplate is 'formed with a pair of openings 6 to receive the keepers 2,7.and

{ the casing byi'liavingits shank slidably sup: ported in theguideway 7 arranged within the casing; The'upper edge of thehead ofthe bolt is rounded so that it will rest against, a part of the casing, and each extremity ofthe head is formed with a. depending part 8 which is of, circular shapein-crosssection and tapers fromits upper end to itsf'lower end so that eachp'artwill conformto the shape of the opening 3 in the keeper. It will, of course, be understoodthat the openings in'the keepers and the parts8 can be of any desired shape, though I prefer-to make these parts arrangementwill cause'the" bolt to drawftlie 'membe'rs together, as theta enter the tapered holes 3.

A headedf'stem 9.is con 7 ing in the top-offthecasing and a spring 10, arranged in the casing, hasits upper end engaging areduced' part on" the lower "end of the bolt and it'sjot'her endengaging apin 11 carried by theca'sing so that this spring tends to hold the bolt in; raisedand inoperative positio'n. The lower end of the bolt is formed .i with a notch12 for receiving a spring actuated- .a T-shap'ed bolt 6 is'slidably supported in'i of the shape shown-in'the drawings, as this i 1 Fe Parts V nected withthe I 1* head of the bolt and passes throughanopenlatch 13 so that the latch will hold the bolt in lowered and locking position. The bolt, below the notch, is beveled to engage a beveled end of the latch 13, so that when the bolt is depressed by means of the stem 9, its beveled part, striking the beveled part of the latch 13, will force the latch outwardly against the action of its spring 14, and then, when the notch 12 comes opposite the latch, the

\ spring 14 will project the latch into the notch. The latch is moved to inoperative position through means of the pins 15 engaging the arms 16 on the latch, the pins be.- ing carried by a member 17 which is con nected with the barrel or cylinder 18 ot a members A and B are brought together.

Then by depressing the bolt through means of its stem 9, the parts 8 will enter the openings 3 in the keepers and as the bolt is depressed, the latch-13 will be caused to engage the notch 12 so that the bolt is held in depressed position, with its parts 8 in the openings of the keepers and thus the two members are firmly lockedtogether.

Attention is called to the fact that the keepers are entirely concealed in the lock casing and that the casing covers the plates 1 so that it is practically impossible for a person to gain access to the building through the doors or other barriers which are held closed by this improved lock. The cover plate is also concealed so that this plate cannot be removed. This arrangement avoids the use of hasps and shackles which are easily sawed or otherwise damaged by persons desiring to enter a building.

The lock also aterproof, as the head of the stem 9 is so formed that it entirely covers the opening through which the stem passes, and the keyhole is arranged in the bottom of the lock so that no water or moisture can enter therethrough.

If desired. a'chain or other flexible member 21 can connect the stem with one of the members A or B, as shown in Figure 1, so that the lock will remain attached to one of the members when not in use.

In the modification shown in Figure 9, the keepers are placed on a circular plate 22 which is attached by a chain 23 or the like to the head of the stem, this arrangement being useful as a lock for locking a spare tire to a vehicle, for instance, or this arrangement can be used as a handcuti'.

Figure shows the lock slightly modified so that it can be used with a pair of members,

wherein one of the keepers 2 is arranged at ri ht angles to the other keeper. In this case, one of the openings 6 in the lock casing would extend through one side of the cover plate and through one side of the casing so that v the keeper member 2 can readily enter the casing when the two members A and B are brought together. In other respects, this form of the invention is similar to that first described.

Figure 11 shows another modification in which the latch means for holding the bolt an extension 24 on the lower part of the casing where the key barrel enters the same, as shown, this extension acting to prevent moisture entering the casing'by running down the sides thereof and entering. the keyhole.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made inthe construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

hat I claim is 1".A lock of the class described comprising a casing having keeper receiving openings therein, a pair of keepers for entering the openings, each keeper having an opening therein, a- T-shaped bolt located in the casing and slidably mounted therein and having a depending part on each end of its head part for'engaging the openings in the keepers when the bolt is moved to a certain position, spring means for normally holding the bolt in inoperative position within the casing and key operated means for holding the bolt in looking position in the casing.

2. A lock of the class described comprising a casing of circular form and having flat faces and having a pair of openings in one face, a. pair of keepers entering the openings, said keepers being entirely concealed by the casing, a T-shaped bolt slidably supported in the casing and enclosed thereby and having a pair of members, one at each end of the head thereof for engaging the keepers when the bolt is moved toa certain position, spring means for normally holding the bolt in unlocking position, key operated latch means for holding the bolt in locking position and a stem on the bolt passing through an opening in the casing for moving the bolt to locking position.

3. A lock of the class described comprising a casing of circular shape with flat faces, one face having keeper receiving openings therein, keepers for entering the openings, at T- shaped bolt slidably arranged in the casing and having its upper edge rounded? to con form to the shape of the casing with depending parts at the ends of its'head for engaging the keepers aspring'for normally holding the bolt in unlocking position, a key cylinder extending upwardly through the lower part of the casing, a latchmember operated by the turning movementof the cylinder for holdingthe bolt in looking position anda fsteln on the bolt passing'throughan opening in the top of the casing. l I

In testimony whereof I aifix my signature.
